As temperatures drop and days get shorter, winter can put extra pressure on rental homes – and on landlords. Whether you’re managing a city centre flat or a family home in Roath or Canton, it’s essential to keep your property protected and your tenants comfortable.
Here’s a simple winter-ready checklist to help you stay on top of maintenance, avoid costly callouts, and meet your legal responsibilities as a landlord in Cardiff.
Check the heating system early
Don’t wait for the first cold snap to test the boiler. Ask your tenants if it’s working efficiently, and book a service if one hasn’t been done in the past 12 months.
A working heating system isn’t just about comfort – under the Homes (Fitness for Human Habitation) Act, properties must be free from hazards such as cold and damp. A boiler breakdown in mid-December is inconvenient for everyone, so prevention is key.
Tip: Check radiators are heating evenly and bleed them if needed. This can help tenants stay warm without turning up the thermostat.
Insulate against draughts
Energy bills are a concern for many tenants, especially during winter. You can help improve energy efficiency by checking for draughts and insulating where needed.
- Fit draught excluders to doors
- Seal gaps around windows
- Ensure letterboxes and keyholes are covered
Even small changes can reduce heat loss – and make your property more attractive to prospective tenants.
Clear gutters and check the roof
Blocked gutters can cause rainwater to overflow, leading to damp walls and potential damage to brickwork. Make sure all gutters and downpipes are clear of leaves, moss and debris.
While you’re at it, visually inspect the roof. Missing or damaged tiles can quickly become a bigger issue in wet or icy weather.
If your property is a flat, confirm with the managing agent that shared maintenance is up to date.
Test smoke and carbon monoxide alarms
By law, landlords in Wales must install a working smoke alarm on every storey of a property used as living accommodation, and a carbon monoxide alarm in any room with a gas, oil or solid fuel appliance.
You’re also required to ensure they’re in working order at the start of each new tenancy, but it’s good practice to check them before winter sets in.
Did you know? Tenants are responsible for regularly testing alarms, but you can support them by leaving clear instructions or checking during inspections.
Prepare for storms and cold snaps
Welsh winters can be unpredictable, so it’s worth taking extra steps to prevent weather-related issues:
- Secure loose fence panels or garden furniture
- Check external pipes are lagged to prevent freezing
- Leave clear contact details for emergency repairs
Encouraging good communication with your tenants helps ensure small problems don’t become big ones.
Keep your property compliant
Winter is a good time to review your certificates and paperwork too:
- Gas safety certificate (annual)
- Electrical installation condition report (every 5 years)
- Energy performance certificate (EPC, valid for 10 years)
Being up to date means you’re ready for new tenancies and avoid fines or enforcement action.
